LOS ANGELES, July 6 — In what is easily his most demanding role since finishing the Harry Potter franchise, Radcliffe plays an FBI agent posing as a white supremacist in Daniel Ragussis's directorial debut.

Based on a true story, Radcliffe plays Nate Foster, an up and coming agent who has to thwart a far-right terrorist group from the inside and must do so by sticking to a very uncomfortable cover story without letting his true feelings become warped in the process.

The film, which also stars Toni Collette, will hit US cinemas on August 19. — AFP-Relaxnews
